Utility of a Modified Oropharyngeal Airway for Performing Tracheal Intubation Using a Fiberoptic Bronchoscope and Video Stylet: A Randomized Crossover Trial Using a Manikin

Figure 2

The appearance of the video stylet and the fiberoptic bronchoscope. The video stylet (VL400-S3 model from UE Medical Corp.) has a preformed semirigid stylet that is about 30 cm, almost the same as the tube, and the monitor is attached to the body of video stylet (a). The fiberoptic bronchoscope (aScopeTM 3 Regular 5.0/2.2 model from Ambu ®) has a long fiberscope that is about 60 cm, so the tube can be placed only in the proximal part of the fiberscope, and the monitor should be placed elsewhere in the table. However, the tip of the fiberscope can be manipulated by the level in the body of the fiberoptic bronchoscope (b).
